In practice, units proportional to frequency, (wave number in units of cm-1) rather than wavelength, are commonly used and the region 2.5 to 15 ?corresponds to approximately 4000 to 600 cm-1. Absorption of radiation in this region by a typical organic molecule results in the excitation of vibrational, rotational and bending modes, while the molecule itself remains in its electronic ground state.
